The watch comes with a set of silicone straps, a charging dock, and a cable for debugging and programming. It should be noted the development kit is solely for development purposes, and if you buy this as a end-user you’ll be disappointed as the firmware is not quite ready. Instead, the kit is intended for developers who will work on OS development for the PineTime.
Firmware & software support for PineTime will entirely be dependent on community efforts, and as such there aren’t any schedule or ETA. If you want to follow the development and/or join the fun, PineTime development group on Telegram currently had 100 members. Lup Yuen Lee got an early development kit sample to port Apache Mynewt OS and Embedded Rust to the watch, but he also found out it’s a good tool to teach IoT and wrote about his initial experience on Medium.
